3U cPCI Multifunction I/O Boards

Configurable 3U cPCI Multifunction I/O Boards

NAI offers a variety of rugged 3U CompactPCI Boards – designed to be combined with our pre-integrated smart function modules – to create a highly flexible COTS-based solution ideally suited for I/O intensive sense, response and communications requirements.

With over 70 pre-integrated I/O, measurement, simulation or communication functions to choose from, NAI’s modular IO approach provides unmatched levels of design flexibility, channel density and SWaP optimization.

Optimized to deliver unusually high-function density, high resolution / accuracy and low power consumption for rugged defense, commercial aerospace, and industrial applications, NAI’s intelligent 3U CompactPCI cards can often operate as standalone systems, eliminating the need for a Single Board Computer (SBC), operating system and associated software royalty costs.
